Cracked PIG spawns big berg

NASA’s IceBridge operation for this Antarctic summer has discovered that the Pine Island Glacier is in the process of calving a massive iceberg — 880 square kilometres of the floating glacier tongue is about to go floatabout, leaving the glacier snout shorter than any time since its position was first recorded in the 1940s. The crack was first spotted by a flight on October 14, and surveyed during a flight on the 28th — featured in the video above. NASA’s Earth Observatory has more pictures and commentary, and there’s a background piece for the video at the NASA IceBridge news page.
